SPECIFICATION forming part of I etters' Patent N 0. 293,416, dated February 12, 1884., Application filed September-21,1883. (No model.)

To all whom it may concern.-

Be it known that I, WALLACE H. CARTER,

' of Farmingdale, in the county of Kennebec and turns on the pintle at a, 35

State of Maine, have ful Improvement in Scuttle-Hi1] ges, which improvementis fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a sectional view of my invention attached to a scuttle or trap-door closed,

and Fig. 2 the same open.

The object of my invention is to construct a hinge that may be applied to a trap-door or scuttle, so that when the same is closed there is no projection on the upper or floor side, but it is all even with the floor.

Like letters of reference indicate like parts.

In the drawings, Fig. 1, a is the trap-door or scuttle,- b, the floor at side of same; 0, one leaf of hinge, secured to the door or sentt.e by the screws 1 1, and the parts 01 and 6 thereof form an arm making part of the leaf. The section (I is part of an arc of a circle around the pintle n, and the section 6 is made straight, as indicated, and the whole is joined'at n to the leaf f, which is constructed in any convenient form, and secured by the screws 2 2. The sides of the floor and scuttle are beveled at g and h, so they will not interfere when open- 1ng.

Fig. 2 shows the door or scuttle open.

The operation of the whole is readily understood. When the scuttle is raised, the hinge and the section of the leaf cl passes by the side buntil the section 6 comes against same and the scuttle or door is held in position, as in Fig. 2. The scuttlecover is held up from the floor, and the floor may be swept or cleaned without interfering therewith. The arm 01 is made of sufficient to incline from the Fig. 2. This causes it center of gravity is car- When the scuttle length to allow the cover opening, as shown in to remain open, as the ried back of the pintle n.

invented a new and useused in any is closed, there is no projection on the upper or floor side, and it may be swept or worked upon without interference.

On places where the floor is wet this hinge has a great advantage in being fastened away from the side of the scuttle.

tage of this construction is that it does not have a tendency to catch any substance in the joint at g h, as the parts slide by each other when opened or closed.

WVhile this hinge is intended more particularly for scuttles and trap-doors, it may be position where it isnot desirable to have the hinges exposed,,and though this is the more compact form, it is evident that the arm of the leaf (1 may be made straight and the section 6 longer. a

The manner of securing to the scuttle or side may be varied to suit the place and work to be done.

It will be seen that my hinge, as constructed, can be applied to floors of different thicknesses and will operate equally well, the sides of the cover and floor being beveled, as de scribed.

I am aware that a concealed hinge 'is not new; but I believe that the peculiar construction of the leaf 0 cl 6, so applied that the scuttle will remain open and the cover be held clear of the floor, and the capability of application to different thicknesses of floors, are material improvements.

I claim as my invention- The hinge herein described, consisting of a part, c, for connection with the door, the part 6, pivoted to a bracket or equivalent device secured to the .floor, and the segment d, connecting the parts 0 and e, the whole being arranged and operating substantially as described.
